Transverse Mode

 

Let's consider a surface 1x1cm² of a 25µm thick mono-oriented PVDF film (d31=16pC/N) stretched along the 1 axis by a 1N force :
 
 
 
 
As the capacitance: C = 0.4nF, a voltage mode measurement, the amplitude of the signal will be 15V.
 
The application field of piezo polymer films is very wide, including :
Force and pressure gauges - Microphones - Hydrophones - Ultrasonic transmitter-receiver - Impact localisation - Displacement detection - Medical imaging - Micro-actuators - Infra-red detection - Active vibration control...
